// Creates a throwaway Postgres database per test-file run against the
|
|
// docker-compose `db` service, points DATABASE_URL at it so tests never
|
|
// touch a shared dev database, and drops it afterwards. Mirrors the old
|
|
// sqlite temp-file-per-run isolation, adapted to Postgres (CREATE/DROP
|
|
// DATABASE instead of a throwaway file).
|
|
//
|
|
// Creating/dropping the throwaway database itself stays raw `pg` (test
|
|
// infra, not the app's data-access layer) — but applying the schema to the
|
|
// fresh database, and tearing down the pooled connection afterwards, now
|
|
// goes through Prisma instead of the old db.ts.
